Abstract (en)
A fiber laminate W is configured by laminating first to fourth fiber layers. The fiber laminate is provided with a taper section, in which the thickness changes depending on the position in the longitudinal direction. The first to fourth fiber layers are formed by discontinuous fibers and are configured with the orientation angles of the discontinuous fibers aligned in one direction. The orientation angles of the discontinuous fibers in the first to fourth fiber layers are different. In addition, the first to fourth fiber layers are provided with thickness changing sections, in which the thickness changes continuously while the density of fibers is kept constant irrespective of the position in the longitudinal direction. The taper section is configured by stacking the thickness changing sections. The change amount of the thickness of each thickness changing section is the same irrespective of the position in the longitudinal direction.
